RAZOR-BLADE SHARPENER.

Application filed June 11, 1925. Serial No., 36,403.

To all whom it may concern:

Be it known that I, DOMENICO PACE, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Razor-Blade Sharpeners, of which the following is a specification.

.This invention relates to novel and simple mechanism for renewing or sharpening the.

double edges of safety razor blades, especially of the well-known Gillette type, at a single operation, by the use of four directly geared rotary stropping members.

I attain these objects by the means set- Fig. 5 is a top-plan View; showing the sec* tions fully extended for applying or removing the razor blade.

In the drawing, 2 and 3 represent respectively upper and lower sections of the body or casing, which preferably comprise simi- Q lar substantially U-shaped sheet-metal parts, one of which is inverted, whose corresponding rear-end walls 2o are formed with similar hinge-loops, as 2 3, which are pivotally connectedby a common pintle 4.

The front end walls 2"3 are preferably longer than the normal depth of the sections, and are arranged to be partially overlapped when the sections are closed, as best seen in Fig. 2. The wall 8 is preferably formed with an integral plane lug or latch 3, which extends the full height of the wall 2. The lug 3. is more or "less flexible, and its free end is preferably formed into a hook 3, which conforms to and snaps over-the round corner 2 of the cover, for frictionally holding the sections inthe closed shown in Figs. 1 and 2.

The sharpening of a razor blade, as 5,-is effected by similar upper and lower abrading or stropping rolls, which are preferably arranged in pairs, as 66 and 7-7, between which the blade 5 is disposed; the said blade preferably being held in place by a plurality of similar studs or posts, 1as"8,-which are shown equidistantly spaced, and". engage positlon,

alining holes 5 of the blade. The posts 8 are rigid to the bottom of section 3 (see Figs. 2 and 3). The rolls 6, 7 and 7 may be covered with any suitable abrading or polishing material, as 5", and said rolls are preferably rigid on similar shafts 7 the opposite ends of which may be reduced and journaled in the end walls 22 and, 3-3 as shown in Figs. 2 and 4. The roll 6 is shown mounted upon a shaft 6?, which is journaled respectively in walls 2, 2 of the upper section, one end of said shaft preferably being extended beyond the wall 2 and being bent to form a crank 6 by which the several rolls may. be rotated. The stropping rolls are provided at their front ends with similar spur-gears, as 99 and 10-10', all of which become meshed when the sections are closed, and form, starting with the gear 10 and ending with the gear 10, a continuous direct with each other, and respectively mesh with the lower gears 1010. are not directly meshed, but are preferably spaced to afford clearance for the posts 8.

By this construction and arrangement, the turning of the gear 9 towards the right, by

means of the crank 6, simultaneously rotates all of said gearsin the directions indicated by the arrows in Fig. 3, wherein each stropping roll rotates in the direction away from the longitudinal center of the blade, for effecting the corresponding effective abrading or dressing of the four surfaces adjacent the two cutting edges of the blade... By disposing the stropping rolls according to the peculiar relation shown in Fig. 3,

The gears 1010.

acting train. The upper gears 99' mesh the upper rolls being close together, and the lower rolls being spaced by the posts 8-1 am able to positively and suitably drive the four rollsby the use of but four gears, thus reducing the number of gears and related parts heretofore commonly employed in sharpeners of this class. The crank 6 is preferably applied .to the gear 6, in order :that it may be conveniently rotated without interference with a table or other support. The crank 6", however, may be applied to the roll-7, since the latter must be rotated in the same direction, as roll 6, as shown.

My razor blade sharpener is extremely simple, light and direct acting, having but few parts, and may be operated by a minimum of exertion or power. The stropping rolls, as well as the gears, are respectively of the same dimensions, and may be constructed from common stock, by the same tools. The sections 2 and 3 may be readily and quickly opened and closed, and the whole device is readily portable, and may be stored or packed in a comparatively small space.

Having thus described my invention, what I claim, is

A razor blade sharpener composed of a casing having an upper and a lower section, means to hingedly connect the sections at one end thereof, blade engaging posts connected to the lower section, a pair of lower stropping rolls journaled in the lower section and disposed on opposite sides of the posts, a pair of upper stropping rolls jourra /e204 naled in the upper section and disposed close relation, gears on-the upper rolls 1n mesh with each other, gears on the'lower respective adjacent upper rolls and disposed on opposite sides of the posts, and means to rotate one of the rolls, all of the gears of the rolls being located at the end of the casing opposite to the hinged end thereof so as to permit the opposite ends of the upper and lower rolls to freely approach upon closing movement of the sections about the hinged means thereof.
